THEODORE A. KIMMELL, OF KANSAS orrY, MISSOURI;

FALSE BOTTOM FO-R BOILING KETTLES, PANS, 84c.

SPECIFICATION formingpart of Letters Patent No. 410,248, dated September 3, 1889.

Application filed June 6. 1889. Serial No. 313,308. (No model.) i i To all whom it may concern.-

Be it known that I, THEODORE A. KIMMELL, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in False Bottoms for Boiling Kettles, Pans, &c., of which the following is a full, clear, and exact description, reference being had ,to the accompanying drawings, forming a part hereof.-

My invention relates to improvements in false bottoms for use in boiling kettles, pots, stew-pans, &c., to prevent the contents of the vessel from scorching or burning; and it consists in a certain novel construction, which is fullydescribed hereinafter in connection with the accompanying drawings, and specifically pointed out in the appended claim.

In the present practice movable false bottoms are arranged to rest on flanges or ribs on the sides of the vessels, thereby requiring a special construction of said vessel, or the false bottoms are providedwith short legs or rests to bear on the bottom of the vessel. In the latter case they (the false bottoms) are usually cast.

The object of my invention is to providea simple, cheap, and easily-manufactured device, struck from sheet metal, whichrests directly on the bottom of the vessel, (thereby adapting it to be used in any vessel of a suitable size,) all the parts of the false bottom except the peripheral edge on which it rests being out of contact with the bottom of the vessel, to provide an open space which willprevent the contentsof the vessel from burning when it boils dry.

In the drawings, Figure 1 is a perspective view of a false bottom embodying my invention; and Fig.2 is a central sectional view of the same applied in the operative position to a kettle, the latter being also broken away.

In the construction of my improved false bottom I employ any suitable sheet metalsuch as tin, iron, (either galvanized or*plain,) copper, brass, &c.and I make it of any desired shape, as circular, square, oblong, or elliptical, to suit the shape of the vessel to which it is to be applied. Further, it is preferably formed from a flat sheet of the metal by stamping or pressure, and it is provided with a central depression or concavity surrounded by a raised portion or. rounded rib, and is also provided with a downwardly-curved or flared peripheral edge to bear on the bottom of the vessel.

The false bottom, which is vessel and hold the surface of the false bot: tom out of contact with the bottom of the.

represented in the drawings by the reference-letter'A, is pro:

vided with the central depression or'concavity a, which is surrounded by the raisedportion or rounded rib I), having at its apex an annular series of perforations B B, said series 0on sisting of two or more rows of perforations, as

preferred. The out-er edge of the false bot-.

tom is curved or flared downwardly, as shown at a, to rest on thebottom of the vessel, which is represented by the letter C in Fig 2. It

will be observed that the central depressed portion of the false bottom is in close proxcontact therewith, owing to the fact thatthe edge 0. extends below the plane of the said depression. cavity serves to concentrate the solid portlon of the contents of the vessel, or draw them inward away from the sides of the vessel, and as the surface of the same is imperforate, as

shown, there are no obstructions to interfere.

with the use of a spoon or other utensil in stirring or agitating the contents of the vessel.

This centraldepression or con-,

The object in placing the perforation in the annular raised portion or roundedrib is that the contents of the vessel are not liable to accumulate at this place and close the perforations, and thereby interfere with the circnla tion of heated water therethrough.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, lS I i As an improved articleof manufacture, the herein-described false bottom for culinary vessels, the same struck from sheet metal and having a central concavity or depression surrounded byaraised and rounded rib b, which is provided with a series 6f perforations B,

and a depending outwardly-flared flange a,

the lower edge of \vhich jis slightly below the.
